How to sort names correctly in php?

Question

PHP

All the same, the question remained ...
I used it like this:

usort($results, function($a, $b){
return strcmp(str_replace('.', '', $a['name']), str_replace('.', '', $b['name']));
});

Received the following (forgive me for such a long list, put all that there should be clear):

Cast strings to the same case if you want to sort case-insensitively:

usort($results, function ($a, $b) {
    return strcmp(
        strtoupper(str_replace('.', '', $a['name'])), 
        strtoupper(str_replace('.', '', $b['name']))
    );
});
